제목 Polypropylene-Based Nanocomposites with high mechanical and dielectric strength for High-Voltage Application
초록 With the expansion of high-voltage direct current (HVDC) power cables, increasing attention is paid to polypropylene (PP) as an insulation materials to replace crosslinked polyethylene (XLPE) due to its recyclability and cost-effectiveness. However, PP has disadvantages of mechanical brittleness and low thermal conductivity compared to XLPE. Improvement of dielectric strength is important because it can provide safe and reliable performance, thus enabling reduction of the insulation thickness and increase of heat dissipation. In this study, polyolefin elastomer (POE) was selected to as a blending material to improve the mechanical flexibility, and nanocomposites were manufactured based on PP/POE blending to improve dielectric and mechanical performances. Sol-gel method was employed for synthesis and surface modification of inorganic nanoparticles, the proper surface modification played a decisive role in obtaining high dielectric and mechanical strength.
